Floxin Prescribing Information

Floxin is a type of Fluoroquinolone antibiotic which is used to fight and treat the symptoms of bacterial infections in our body. Basically, Floxin belongs to the Fluoroquinolone class of antibiotics and the most crucial ingredient of Floxin is known as ofloxacin. To be precise, Floxinofloxacin is used to treat and cure the symptoms of bacterial infections which are related to the epidermis, skin, lungs, respiratory system, nervous system, prostate glands as well as the liver and kidneys of our body. Apart from these common bacterial infections,Floxin of succession is also required to cure the symptoms of pelvic inflammatory disease and Gonorrhoea.

Apart from all the curing effects of Floxin or Ofloxacin, it should also be remembered that since it is an antibiotic, hence the consumption of ofloxacin might lead to some serious side effects which can be really lethal and dangerous for the well being of an individual.

Uses of Floxin

Some common uses of Floxin include:

  • Urinary Tract Infections (UTIs): Floxin is often prescribed to treat uncomplicated and complicated urinary tract infections caused by susceptible bacteria.
  • Respiratory Tract Infections: It can be used to treat infections such as bronchitis, community-acquired pneumonia, and sinusitis caused by certain bacteria.
  • Skin and Soft Tissue Infections: Medicine can be used to treat bacterial skin infections, including cellulitis, wound infections, and abscesses.
  • Sexually Transmitted Infections (STIs): It can be used to treat certain sexually transmitted infections, such as gonorrhea, when other antibiotics are not suitable.
  • Gastrointestinal Infections: Antibiotic can be used to treat bacterial infections in the gastrointestinal tract, such as infectious diarrhea and traveler's diarrhea.
  • Bone and Joint Infections: In some cases, it may be used to treat infections of bones and joints, although this is less common.
  • Prophylaxis: Floxin might be used as a prophylactic measure to prevent infections in certain high-risk situations, such as in people with weakened immune systems.
  • Other Infections: Ofloxacin might be used in other types of infections, depending on the susceptibility of the bacteria involved and the overall clinical situation.


The dosage of Floxin can vary based on the type of infection being treated, the severity of the infection, the patient's age and weight, and other individual factors. The following dosage information is a general guideline, but it's important to follow the specific instructions provided by your healthcare provider or on the medication label. Never adjust your dosage without consulting your doctor.

Keep in mind that the dosages provided below are general recommendations and can vary. Always follow the instructions provided by your healthcare provider or the medication packaging.

Urinary Tract Infections (UTIs):

  • Uncomplicated UTIs: Typically, a common dosage might be 200 to 400 mg orally every 12 hours for 3 days.
  • Complicated UTIs or pyelonephritis: Dosage might be higher, around 200 to 400 mg orally every 12 hours for 10 to 14 days.

Respiratory Tract Infections:

  • Dosage can range from 200 to 400 mg orally every 12 hours for 7 to 14 days, depending on the severity of the infection.

Skin and Soft Tissue Infections:

  • The usual dosage might be 200 to 400 mg orally every 12 hours for 7 to 14 days.

Gastrointestinal Infections (Diarrhea):

  • Dosage can vary, but a common recommendation is 200 mg orally every 12 hours for 3 days.

While there's no strong evidence of a significant interaction between Floxin and grapefruit juice, it's generally recommended to avoid grapefruit juice when taking any medication.
  • Follow Dosage and Instructions: Always take tablets as prescribed by your healthcare provider. Avoid missing doses or stopping the medication prematurely, even if you start feeling better before the full course is completed.

Contraindications of Floxin

Contraindications are specific situations or conditions in which a medication like Floxin should not be used due to potential risks or interactions. It's crucial to be aware of contraindications to ensure your safety and the effectiveness of the medication. Here are some contraindications associated with this drug:

  • Known Allergy or Hypersensitivity: If you have a known allergy or hypersensitivity to ofloxacin or other fluoroquinolone antibiotics, you should not take Floxin.
  • Tendon Problems: Pharmaceutical product is associated with an increased risk of tendonitis and tendon rupture, particularly in the Achilles tendon. If you have a history of tendon problems or are currently experiencing tendon pain, you should avoid using Floxin.
  • Children and Adolescents: Fluoroquinolone antibiotics, including Floxin, are generally not recommended for children and adolescents, as they can potentially cause musculoskeletal issues and interfere with bone development.
  • Pregnancy and Breastfeeding: Ofloxacin should be used with caution during pregnancy and breastfeeding. The medication may pose risks to the developing fetus or nursing infant. Your healthcare provider will weigh the potential benefits against the risks before prescribing Floxin in these situations.
  • Myasthenia Gravis: Medicine can exacerbate the symptoms of myasthenia gravis, a neuromuscular disorder that causes muscle weakness and fatigue. If you have this condition, Floxin should be avoided.
  • Certain Heart Conditions: Floxin can potentially cause irregular heart rhythms (QT interval prolongation) that can be problematic for individuals with pre-existing heart conditions. If you have a history of heart problems or are taking medications that can affect heart rhythms, Floxin might not be suitable for you.
  • Seizure Disorders: Floxin may lower the seizure threshold and increase the risk of seizures. If you have a history of seizure disorders, the use of Floxin should be approached with caution.
  • Glucose-6-Phosphate Dehydrogenase (G6PD) Deficiency: Floxin can cause hemolytic anemia in individuals with G6PD deficiency. This condition is more common in certain populations, such as people of Mediterranean or African descent.
  • Central Nervous System Disorders: Antibiotic can affect the central nervous system and potentially exacerbate disorders such as epilepsy or other CNS conditions.
  • Interactions with Other Medications: Ofloxacin can interact with certain medications, potentially causing adverse effects or reducing the effectiveness of the medications. It's important to inform your healthcare provider about all the medications and supplements you are taking.
  • Previous Adverse Reactions: If you have previously experienced severe adverse reactions to fluoroquinolone antibiotics, it's advisable to avoid using Floxin.

Pregnancy and Floxin

Antibiotic is generally not recommended for use during pregnancy due to concerns about its potential effects on the developing fetus. The U.S. Food and Drug Administration (FDA) has classified Floxin as a pregnancy Category C drug. This means that animal studies have shown adverse effects on the fetus, but there are no well-controlled studies in pregnant women.

Here are some important points to consider regarding Floxin and pregnancy:

  • Risk to the Fetus: Animal studies have shown that Floxin can cause harm to the developing fetus, including effects on cartilage development. While the exact risks in humans are not fully known, the potential for harm cannot be ruled out.
  • Alternative Antibiotics: In many cases, healthcare providers prefer to avoid fluoroquinolone antibiotics, including Floxin, during pregnancy unless there are no suitable alternatives. Safer antibiotics with a known safety profile in pregnancy are often preferred to minimize potential risks.
  • Discuss with Your Healthcare Provider: If you are pregnant or planning to become pregnant and your healthcare provider has prescribed antibiotic, it's crucial to have an open discussion about the risks and benefits. Your doctor will consider your specific situation and determine whether the potential benefits of treating an infection with Floxin outweigh the potential risks to the fetus.
  • Breastfeeding: Ofloxacin can pass into breast milk, potentially affecting a nursing infant. Therefore, it's generally recommended to avoid Floxin while breastfeeding. If you need to take an antibiotic while breastfeeding, your healthcare provider will help you choose a safe alternative.
  • Birth Defects: While there is limited data on the direct association between Floxin and birth defects in humans, some fluoroquinolone antibiotics have been associated with an increased risk of certain birth defects.
